Why it matters

What doing nothing costs you.

They search. They call someone else.

If you are not near the top on Google, the customer calls whoever is. You never even hear about it.

Your site stalls. They hit back.

People on a phone do not wait for a slow page. They leave before they ever see your work.

No quick way to call. The job walks.

If calling or booking takes more than a tap, they try the next business on the list.

See which of these is costing you. Free, in 60 seconds.

Common questions

Web development in St. Louis, answered.

Do you build websites for St. Louis businesses?
Yes. Corestack builds custom websites, local SEO, Google and Facebook ads, and AI receptionists for businesses in St. Louis and across Eastern Missouri. We are a Missouri agency based in Columbia, so working with a St. Louis client is straightforward, remote or in person.
I already have a website. Why would I need you?
Having a website is not the same as having one that works. Most St. Louis sites we look at load slow, bury the phone number, and never rank on Google for the searches that matter. If yours is quietly losing customers, we find it and fix it. Run the free audit and see for yourself, no pressure to switch.
Can you fix my current site, or only build new ones?
Both. If the bones are solid, we tune what is costing you leads and speed. If the platform is holding you back, a clean rebuild pays for itself fast. The audit tells us which one you are, and we tell you the honest answer either way.
How much does a website cost in St. Louis?
Pricing is fixed and transparent. Websites start at $1,200, and every project gets an exact quote from a short questionnaire before any work begins. No hourly surprises and no padded estimates.
How fast can you launch a site for my St. Louis business?
We lock the timeline before we start, so you always know your launch date. It depends on the size of the site and how fast content and access come in.
Do I own the website when it is done?
Yes. You own the site, the code, and the domain from day one. No lock-in, no holding your project hostage. That is true for every St. Louis client.
Can you help if I already have a site near the Gateway Arch?
Absolutely. Start with the free AI audit. It scores your current site in about 60 seconds and shows exactly what is costing you customers, then we fix what matters.

Let's get your phone ringing.

A free 15-minute call. You leave knowing exactly what to fix first.
